Haney, who is working with the singer as a part of a one-hour special called Celebrity Closet Confidential, explains that while Rimes has always been able to pull off a sexy outfit, it's Haney's hope that she'd find a more refined style without losing her allure.

"LeAnn's wedding dress had exactly the right amount of sexiness and sophistication," Haney said. "I want to take that and incorporate it in every other aspect of her fashion life."

The gown Rimes wore during her 2011 "I do's" with Eddie Cibrian was inspired by the Grammy dress she wore just weeks before the ceremony.

"Eddie makes me feel sexy and sensual, so I really wanted to bring that off in the dress," Rimes said.
